There is an open position (Project Associate) in this organisation which initially asks for 2 assignments which are both lengthy and challenging tasks. I completed these tasks and submitted them. I have been emailing them for a month for an update but still no reply. So as a last resort I had messaged one of their employees to get an update on the position and after a month I found out they are not even hiring for this position. It is annoying for a renowned organization like Khan academy to be this unprofessional and unethical.
